Abstract
The reaction of vanadyl acetylacetonate with N,N′-bis (salicylidene)-1,5-diimino-3-azapentane (H2SDA) affords an oxo-bridged dinuclear Schiff base vanadium(V) complex, [VO2(HSDA)]2. The structure of the complex was characterized by elemental analysis, infrared spectroscopy, and single-crystal X-ray diffraction. The complex crystallizes as monoclinic space group P21/n, with a = 6.619(2), b = 32.592(3), c = 8.715(2) Å, β = 104.001(3)°, V = 1824.2(7) Å3, Z = 4, R 1 = 0.0637, wR 2 = 0.1228 for 1989 observed data. The complex exhibits a distorted octahedral geometry, involving in the equatorial plane the phenolate, imine, and amine donors of the Schiff base ligand and the bridging oxo O group and in the axial positions two other oxo O groups. The intramolecular V···V distance is 3.226(1) Å.
